frostily

The word 'frostily' is built upon the Old English noun 'frost,' which descends from the Proto-Germanic frustaz, meaning "frost." This, in turn, can be traced back to the Proto-Indo-European root preus-, meaning "to freeze" or "to burn" (referring to the biting cold). The core meaning of 'frost' as the icy crystals formed from frozen water vapor evolved metaphorically to describe a cold, rigid, or unfriendly demeanor. By adding the adverbial suffix '-ly,' derived from an Old English word meaning "body" or "form" which came to indicate manner, the word 'frostily' was formed to describe an action performed with the chilling, unwelcoming quality of frost.
